Seneca Caverns Season Set to 'Crack' Open

April 21, 2022

Join us for a unique experience at Seneca Caverns – Ohio’s Greatest Natural Underground Adventure as they kick off their 2022 season on April 30! Their hours are from 10:00 am to 5:00 pm on Saturday and Sunday with the last cave tour departing at 4:00 pm. Beginning Memorial Day Weekend through Labor Day they are open seven days a week from 9:00 am to 7:00 pm with the last cave tour departing at 6:00 pm.

Get a peek at what is under the ground that we walk on every day. Walk the natural stone steps and pathways that will lead you through seven rooms or levels. Feel the temperature cool as you progress into the cavern. The largest room is 250 feet in length. At the lowest level, 110 feet below the surface, see Ole’ Mist’ry River; the crystal-clear flowing stream which is part of the vast groundwater system underlying the surrounding region. You will be amazed as you enjoy this very unique tour!

Seneca Caverns has been retained close to its original, natural, wild state, this subterranean tour is truly a unique and educational experience you will always remember.

After the tour, try your hand at mining just like they did in frontier days at the Seneca Mining Company. This “gem” is a fully operational sluice with flowing water. Here you can pan for gemstones, minerals, crystals, arrowheads, and fossils.

Seneca Caverns may be the only cave of its kind open for public visitation. Seneca Caverns is a Registered Natural Landmark by the Ohio Department of Natural Resources. Seneca Caverns is open from May through October, rain or shine. Visit to plan your underground adventure!
